Job Huichinson Patented July 4, 1950 UNITEDSTATES PATENT iOF'F'ICE WASHI G MACHINEDBIVE I Job Hutchinson, GreatNeck; NY. nppiieaeenseetember 23, 1947; serial No. 7751.576 1 invention'relates'to' new and useful improvements in washing devices'an'd hasparticular reference to washers which can be easily and quickly placedinto andremoved from tube or basins asauiiit.

It is an object of this invention topi'ovide a simple, compact, "washingdevicewhichcan be placed into'a til-band connected to a source of power'to' effectively agitate the water in which it 'is' placed while'at'thesame time "being entirely immune from said liquid while in the tub.

Further, it is an object to provides. simple rugged device composed ofcomponent units which can be assembled with ease'and with equal easetaken apart for replacement, inspection, and repair. I

A further object is to provide a device wherein the various unitsforming the complete unit can ice manufactured separately and thenquickly assembled so'as-to reduce cost'and labor involved in themanufacture of the-deV-iceand so that when one unit wears out it can bereplaced without the customer having to. buy a completenew unit.

Further and more specific objects; features and advantageswill moreclearly appear from a consideration' of the-detailed specificationhereinafter set forth especially when'taken in connectionwith theaccompanyingdrawings which illustrate several forms which the inventionmay assumeand Which forms 'part of the specification.

In brief and general terms theinvention concerns the provision ofacasing-having an oscil'latable cap'on'which are removably disposedpaddles preferably extending down along the side of the casing. Withinthe casing is a motor'and gear worm unit also separately removable as aunit therefrom a'nd'inclu'ding-drive elemerits such as disks with-eccentric pins thereon'pi'eferably driven in opposite directions. Onthe cap is disposed a driven element which may hinthe form 'of adependent element or flange engaged by 'thepins so as to be os cillatedlba'ck and forth to oscillate the ca and thus the paddles. In "one formthe driven element may includeseparate pivoted dependent arms backed byafspring to engage thepins and increase the quietness ofthe operation. 1

Referring now'merely to the preferred form of the 'inv'entions'hown inthe drawingspit is seen that" there is provided a casing H3, preferablycylindrical in section and of considerable depth, closed at the bottomand open at the top. To this 'cas'ingis'integrally connected a muchlarger base l I. III and theup'per face of the base plate I! areprovided with reinforcing ribs l2 in order to give the same effect tothe clothes as would'loe given by a'was'hboa'rd. v

The casing It is provided with an oscillatable cap I3 having aperipheral flange I4 fitting in a liquid tight manner around the upperedge of the casing. To the top of this cap l3 are removably fastened apair of paddles l5 by means of-bolts I6. These paddles have aperturedportions l1 extending down along the sides'of the casing I I]. In themodified form of'paddle shown in Fig. 4, the paddles have an extensionl8 which may be supported therefrom on extension rods 19 seated insuitablebores in the main portion of the paddle l5.

Connected to the underside ofthe cap l3by erred formwhich the invention-The outer walls of the casingmeans of bolts 20 (see Fig. 3) is a drivenplate or element 2| having a chord-like dependent integral flange 22.This is adapted to be engaged byeccentric pins 23 mounted on disks 24supported on disk shafts 25. These disks are disposed above a frameformed by connected spaced plates 26 and 21 and between these plates thedisk shafts 25 are connected to worm gears 28 driven by a common worm 29on a shaft 3|] carrying a belt pulley 3| connected by a belt 32 to asimilar pulley 33 on a shaft 34 of a motor 35. This. motor is mounted inany suitable manner on a base plate 36 having on its under side a groove31 adapted to receive a rib 38 formed on the floor of the casing l anddiametrically disposed on said floo-r. The frame plates 26 and 21 aresupported from the plate 36 by means of legs 39. It will be clear thenthat the disks, their operating gears, the motor and the connectionsbetween the motor and the gear train are one unit supported within thecasing and separable therefrom merely bybeing lifted therefrom asdesired. It is also clear that the cap and the paddles are separable andthat the cap and/or the paddles can be removed as a unit from the casingsince the driven flange 22 is not positively connected to the drivingpins. It is shown that the disks drive the pins in opposite directions.

In the modified form shown in Fig. 6, the flange 22 is cut away onopposite-sides of its central hub 40 and in these cut-away portions arepivotally disposed arms 4| to be engaged by the pins 23. These arms arebacked resiliently by a spring plate 42 fastened to the hub 40 and areintended to resist the thrust of the pins on the arms. This constructionwill permit a more quiet operation than the one shown in Fig. 1. Thearms 4| are dependent essentially from the cap through the intermediaryof the flange 22 in which they are disposed.

In order to bring electric power into the casing it is accomplished inthe following manner:

The motor wires 43 are passed through a hole in a boss element 44disposed centrally on top of the frame plate into which is screwed onethreaded end 44 of a hollow bushing 45 which passes through a centralhole in the flange plate 2|. The opposite threaded end 46 of saidbushing is screwed into a recess in the bottom of a cup-shapedreceptacle 4'! disposed in the bore of an upright sleeve 43 integralwith the cap l3. In this receptacle is disposed any suitable connectionbox 49 from which wires 50 may be led to a source of power. Surroundingthe top of the box 49 and the receptacle 41 is a cup of insulatingmaterial which can be slipped over these elements in a suitably tightmanner.

In Fig. is shown the casing ID with the cap l3 and to the side walls ofthe casing is attached by any suitable means an overflow pipe 52extending down to the drain outlet in the bottom of the basin in whichthe device is disposed. The top of the pipe 52 is disposed at apredetermined level so that there will be an overflow when the liquid inthe tank or basin reaches a e finite level. It is also seen that thebottom of the base plate H is provided with rubber suction disks 53 atspaced points to facilitate the firm adherence of the device within thethe pin passes around and away from this portion of the flange. At thesame time the other pin has been moving counter-clock-Wise and willengage the other end of the flange as it reaches its furthest clock-wiseswing and this engagement will then oscillate the flange back in acounterclock-wise direction to its former position. Thus the cap and itsattached paddles will be oscillated back and forth and effect thewashing desired.

The auxiliary paddle blades l8 are'shown to obtain a more thoroughmovement of the liquid when the dimensions of the tub or basin permit.It is seen that the device comprises four main separable parts. Firstthe paddles can be easily removed from the cap; second the cap and theflangeor driven element thereon can be lifted readily out of the casing;third the power unit comprising the motor, the gear train and the diskscan be lifted right out of the casing when the cap is removed; andfourth the casing itself which can be firmly adhered to the bottom ofthe basin but as readily removed when desired. Thus all-parts can bereadily taken apart at any time with ease and dispatch for replacement,inspection, and repair as wished.

While my machine is waterproof and can be immersed without danger ofleakage, an auxiliary shield member 55 is provided to extend over thebelt pulley 3| and down to the base. By the same token, on the otherside of the machine is furnished a shield member 56 to completely shieldthe motor in the event that any water should be splashed into themechanism.

As shown in Figures 8 and 9 the casing it may be permanently Welded orbuilt into the sink unit 69, having a conventional dish sink El and atub operation 62. In the particular housing shown there is providedbetween the tubs a rib 63 upon which the wringer can be mounted.

In all respects the operation of the machine is as heretofore described.I

While the invention has been described in detail with respect to presentpreferred forms which it may assume, it is not to be limited to suchdetails and forms since many changes and modifications may be made inthe invention without departing from the spirit and scope of theinvention in its broadest aspects.
